Power Supply Recommendations

Due to the fast output edges, it is critical to have bypass capacitors on the supply pin to prevent supply ringing and false triggers and oscillations. Bypass the supply directly at each device with a low ESR 0.1 µF ceramic bypass capacitor directly between VCC pin and ground pins. Narrow, peak currents will be drawn during the output transition time, particularly for the push-pull output device. These narrow pulses can cause un-bypassed supply lines and poor grounds to ring, possibly causing variation that can eat into the input voltage range and create an inaccurate comparison or even oscillations.

The device may also be powered from "split" supplies (V+, V- and GND), with V- applied to the GND pin.

Input signals must stay within the specified input range (between V+ and V-) for both supply types.

Note that the ouptut will now swing "low" (VOL) to V- potential and not system GND on split supplies.
